GN 464.2-NI Knurled Screws Stainless steel

Knurled screws GN 464.2 are used, for example, to fasten machine covers. The shank d₄ provides simple loss prevention. Instead of a through-hole, this requires a second thread d₁, potentially with a corresponding clearance bore d₅.

Depending on the design and required clamping thickness a₁ ... a₃ of the cover, there are a number of assembly options as shown.
